The utility model discloses a high -efficient drying device for chemical fertilizer production, including drying box, the top one side of drying box is provided with the feed inlet, the both sides of drying box are provided with the ventilation groove that penetrates, the inner chamber of drying box is provided with first mounting bracket, second mounting bracket and guide table from top to bottom in proper order, the one end of guide table extends to the outside of drying box, all are installed with conveyer belt on first mounting bracket, second mounting bracket and guide table, the middle position of conveyer belt is provided with heating assembly, the both sides of first mounting bracket and second mounting bracket are provided with auxiliary drying mechanism, and the chemical fertilizer particle is sent into drying box through feed inlet, makes it fall into the conveyer belt of first mounting bracket, heats and dries through heating assembly to chemical fertilizer, falls to the conveyer belt of second mounting bracket and guide table in proper order after chemical fertilizer moves to the one end of conveyer belt, can turn over chemical fertilizer particle in the process of conveyer belt feeding, improves the drying efficiency of chemical fertilizer.

The present application relates to freeze-drying equipment technical field, disclose a kind of alcohol-free magnetic bead method virus extract freeze-drying equipment, including base, the upper surface of the base is rotatably installed carousel, the circumference direction of the carousel upper surface is equidistantly opened four counterbores, the inside of the counterbores is placed with glass dish.The square column drives driving block to move close to carousel, driving block drives two C-shaped clamps to move away from each other by driving groove and driving column, at this time, cap will fall into the glass dish below, seals the port of glass dish, through the device, cap can be timely covered on the port of glass dish after virus extract in glass dish is dried out, avoid external moisture into glass dish inside, affect the drying of virus extract, at the same time, avoid experimenter manually one by one to cover cap on glass dish, reduce the workload of experimenter.

The utility model discloses a laboratory multilayer airing device, which relates to the technical field of airing devices and is provided with at least two layers of airing structures comprising water tanks, supports, draining pipes and draining plates. The top of the water tank is open, the bottom is communicated with the draining pipe, the draining plate covers the opening of the water tank, and a through mounting hole is formed in the draining plate; in the airing structures, the airing structures located at the bottom serve as bottom-layer airing structures, and the other airing structures serve as upper-layer airing structures; the draining pipe of the upper-layer airing structure penetrates through the lower mounting hole, extends into the lower water tank, and is fixedly mounted with the lower water tank through a bracket. Water drained by the draining plates in the upper-layer airing structure is collected into the water tank on the same layer and guided into the water tank on the lower layer through the draining pipes on the same layer, the water drained by the draining plates on the upper layer is prevented from falling onto the draining plates on the lower layer to affect airing of articles on the lower layer, the number of the aired articles can be effectively increased, airing efficiency is improved, and the airing effect of the articles on the lower layer is improved. And the airing quality of the aired articles on the lower layer can be guaranteed, and the cleanliness of the laboratory environment can be kept.
